我正在做一些愚蠢的事情，我只是沒有看到它。NHibernate映射約束違規

我只想讓Party Party擁有一組PartyNames，使用下面的映射，並且無法插入帶有違反FK約束的PartyName。如果需要，將發佈目標代碼，但懷疑它是映射。

乾杯，

映射（方）

<class name="Party" table="Parties"> 
    <id name="Id"> 
     <column name="PartyId" /> 
     <generator class="hilo" /> 
    </id> 

    <discriminator column="Type" not-null="true" type="string" />

    <subclass 
     name="Parties.Domain.People.Person, Parties.Domain"

    </subclass>

映射（PartyName）

沒有NameSeeds和Scope的代碼很難回答。 –

@Diego Mijelshon。嗨迭戈，看到更新後的帖子。我還加入了維護雙向關係的代碼 - 我知道它爲SO問題提供了一些代碼。乾杯 – Berryl

嗯，我是對的這是映射和我是正確的，這是愚蠢的

我對混在一起外鍵的列名！

 <set access="field.camelcase-underscore" cascade="all-delete-orphan" inverse="true" name="Names"> 
     <key foreign-key="Party_PartyName_FK"> 
     <column name="PartyNameId" /> ** WRONG, what I had 
     <column name="PartyId" />  ** RIGHT, what I umm, meant 
     </key> 
     <one-to-many class="Parties.Domain.Names.PartyName, Parties.Domain" /> 
    </set>
